Okay, I'm hoping someone can help me understand what I SHOULD have done to properly rebase cygwin 1.7 under Win 7 so it would make nice with BitDefender.
As has been pointed out here before, the combination of cygwin 1.7 and BitDefender 2010 make for one unhappy little user. As a reminder, BitDefender's solution to this issue is to rebase cygwin1.dll as follows: 1) Temporary disable AVC (BitDefender->Antivirus->Advanced Settings, uncheck AVC). [ AVC == "Active Virus Control"] 2) Make sure all cygwin applications are closed. 3) Open a Windows cmd line and enter the following: cd c:\cygwin\bin copy cygwin1.dll cygwin_orig.dll copy cygwin1.dll cygwin_tmp.dll rebase -b 0x35000000 cygwin_tmp.dll copy cygwin_tmp.dll cygwin1.dll 4) Reenable AVC (BitDefender->Antivirus->Advanced Settings, check AVC) I've done the above every time I've re-installed or upgraded cygwin 1.7 beta on this machine (running Win 7), and it's been working. But the last time, I began having problems whenever I'd try and pipe one process to another -- say, the output of a find command into an xargs grep or something. It would lock up the bash window and begin dumping a core file. Being something of an idiot as to how Windows dlls truly (don't) work, I figured maybe some of the cygwin libs and commands which were still colliding with BitDefender's libs, so I decided to combine the BitDefender procedures and values with what was advised by the cygwin rebase doc: /usr/share/doc/Cygwin/rebase-3.0.1.README To wit: 1) shutdown all Cygwin processes and services 2) start ash (do not use bash or rxvt) 3) execute /bin/rebaseall (in the ash window) 4) execute /bin/peflagsall (in the ash window) So here's what I did: 1) Shutdown all Cygwin procs and services; 2) Turned off Active Virus Control so I could run any commands under ash; 3) Started ash; 4) executed /bin/rebaseall in the ash window as follows: $ /bin/rebaseall -b 0x35000000 -v 5) Executed /bin/peflagsall in the ash window as follows: $ /bin/peflagsall 6) Turned BitDefender AVC back on, and fired up rxvt to test. Alas, no joy. When I try to execute any command in the rxvt window under bash, it thinks awhile, then does nothing, as per the transcript below: $ ls $ pwd /home/Ed $ less -i .bashrc $ find . -type f -print $ So my question: Why wouldn't have using rebaseall -b 0x35000000 have worked as well as running rebase -b 0x35000000 against just cygwin1.dll alone?
